Dynamics of wetting explored with inkjet printing — •Jonas Landgraf, Simeon Völkel, and Kai Huang — Experimentalphysik V, Universität Bayreuth, 95440 Bayreuth, Germany

Experiments on sessile drops require precise volume control. However, to control drop volume without altering the solid-liquid or liquid-gas interfaces is challenging. Here, we propose to use a conventional, low cost inkjet printhead to solve this challenge. Taking advantage of the high repeatability [1] and fine resolution of drop volume (23 picoliter), we investigate the dynamics of a sessile drop sitting on an inclined substrate. In addition, we explore the wetting front propagation in a granular monolayer.
